Extreme temperatures can have a large impact on exterior home products such as door components.  High heat can cause aluminum thresholds to bend, bow, or warp not only making the sill difficult to walk on and allowing air and water penetration, but also showing an unsightly result to anyone passing through your door.  Having these problems on a front entrance door can be particularly noticeable to your guests.

To help combat extreme heat, incorporate high temperature materials into the composite adjusting caps and inactive panel components such as the High Temperature Z-Plus Sill.  Choosing sill finishes and caps that are light in color will also help to deflect the heat absorption in the sill.

Rain

No matter how well a home is built, over time water will come in contact with exterior door units.  Water can seep into unprotected wood or leak under the sill into the home, creating rotted door frames or sub flooring.  

To eliminate these unsightly issues, use Z-Series All Composite sills featuring a high dam design to further decrease water contact with the door.  To prevent water wicking up the jamb or mold building up in the frame, use FrameSaver No Rot Exterior Door Frames.  FrameSaver has a lifetime guarantee against rot and insect damage.

Snow

Extreme temperatures can have a large impact on exterior home products such as door components.  Freezing temperatures can cause products to shrink or crack showing unsightly damage to anyone passing through your door.  These issues are difficult to see with snow built up against the house but by spring the damage is done.  No matter how well a home is built, over time water will come in contact with exterior door units.  Water can seep into unprotected wood or leak under the sill into the home, creating rotted door frames or sub flooring.  

To eliminate these unsightly issues, use Z-Series All Composite sills featuring a high dam design to further decrease water contact with the door and thermal sill options to help resist the cold temperatures.  To prevent water wicking up the jamb or mold building up in the frame, use FrameSaver No Rot Exterior Door Frames.  FrameSaver has a lifetime guarantee against rot and insect damage.
